Ordered a small amount of LiftMode's kanna powder extract (0.25g) to get started in nootropics and despite my initial doubts, LiftMode's extract noticeably increases my concentration and focus without me needing to use much in a sitting. Order was delivered in three days with no delays whatsoever and I believe I was effectively communicated to when it came to details about the order and purchasing process. I can see myself buying this product again from this vendor.
